untighten
Make less taut
To untighten is to loosen something that has been tightened—a screw, a bolt, a grip.
The word is less common than loosen but appears in informal speech and technical contexts: Untighten the clamp before adjusting the angle.
It emphasizes reversing a previous tightening action rather than simply making something less tight.
